Futaba "Y" cable

Duplicate connections without complicating your installation with the Futaba "Y" Cable

The Futaba "Y" Cable with reference GF-1120-020 is an electronic accessory for radio control designed to split the signal from one channel into two simultaneous outputs. A simple and effective solution when you need to connect two servos or receivers to the same channel of the transmitter, maintaining signal integrity and avoiding unnecessarily complex wiring.

Function and performance

The "Y" configuration of this cable allows the signal from the receiver to be split into two independent branches. This is particularly useful in setups where two servos are required to work in parallel —for example, in symmetrical control surfaces— or when you want to connect two devices to a single channel without the need for additional electronic multipliers.

As a passive cable, it does not introduce latency or additional processing: the signal reaches both ends directly and simultaneously, ensuring a coherent response in the two connected devices.

Compatibility and installation

This cable uses the standard Futaba connector, one of the most widespread formats in the world of radio control. It is compatible with the vast majority of receivers and servos that use this type of connector, making it easy to integrate into existing installations without the need for adapters.

• Futaba type connector on all three ends of the cable.
• Direct installation without tools or soldering.
• Allows connection of two servos or receivers to a single channel.

Recommended applications

This type of "Y" cable finds its place in multiple areas of radio-controlled modelling:

• Models and RC vehicles: connection of two steering or throttle servos in symmetrical configurations.
• Competition setups: simplification of internal wiring without losing free channels on the receiver.
• Test benches and configuration: simultaneous connection of multiple devices to verify system response.

Considerations

When connecting two servos in parallel via a "Y" cable, the receiver must supply power to both devices simultaneously. It is advisable to check that the power supply and the receiver's regulator have sufficient capacity to manage the combined demand of the two connected servos, especially if they are high-torque or intensive use servos.

Frequently asked questions

Can I use this cable with any brand of servo or receiver?

As long as the device uses the standard Futaba connector (the most common in the RC market), compatibility is guaranteed. If your equipment uses a JR connector or similar, please check beforehand that the pin configuration is compatible.

Does the "Y" cable affect signal quality?

No. As a passive cable without active electronics, it does not degrade or introduce delay in the signal. Both servos or receivers receive exactly the same signal at the same time.

How many "Y" cables can I chain together?

Technically it is possible to chain them, but it is not advisable to do so indiscriminately. Each added branch increases the load on the receiver's channel. For installations with more than two devices per channel, it is preferable to use an active hub or multiplier.

Is it suitable for competition?

Yes, as long as the competition rules do not restrict the number of servos per channel. It is a common solution in club setups and advanced recreational use.

The GF-1120-020 Futaba Y-cable is a reliable RC accessory for splitting one channel signal into two simultaneous outputs, compatible with standard Futaba connectors. Perfect for servo parallel connections in radio-controlled models, competition setups and hobby installations.
